Question

Write the energy conversion taking place in the following device. (A)storage battery (B)Induction cooker

Answer 1

Answer:

A battery stores energy in form of chemical energy which is active in it's chemicals and can be converted into electric energy whenever it is needed. thus inside a battery chemical energy is changed into an electrical energy.

Answer 2

Answer:

(A)storage battery-Chemical energy ⇒ Electrical energy

(B)Induction cooker-Chemical energy ⇒ Heat energy

Explanation:

CASE A: Storage battery

• The presence of certain compounds in a storage battery facilitates the generation of ions.
• In a solution, these ions are free to migrate.
• The rate of flow of charged particles is referred to as the flow of current.
• Ions, which have a charge and may move or flow, aid in the generation of current.

Consequently, energy conversion in a storage battery is

Chemical energy ⇒ Electrical energy

CASE B: Induction cooker

• Inside an induction cooker are coils with comparatively higher resistance.

• Due to resistance, these coils generate heat when current flows through them.

• The formula H=I²Rt yields the heat produced (H)

• To create heat for cooking, current or electric energy is used.

Consequently, the energy conversion in an induction cooker is

Chemical energy ⇒ Heat energy
